RE: You used servlet-mapping to make your servlet work, but what about a JSP page with a bean?
Is your bean in a package? If not Tomcat will not find it in the default package. just add package com.mypackage to bean source, and put class file in classes/com/mypackage ron -Original Message- From: Wilson Snook [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 14, 2003 4:31 PM To: Tomcat Users List Subject: You used servlet-mapping to make your servlet work, but what about a JSP page with a bean? I am a newbie experiencing a very frustrating problem. I have a web application that uses a packaged javabean.

Re: You used servlet-mapping to make your servlet work, but what about a JSP page with a bean?
Thanks Ron, but please note bean is declared to be in: package coreBeans; and directory structure is %TOMCAT_HOME%/webapps/core/WEB-INF/classes/coreBeans/FormBean.class AFAIK that is the correct form, unless you are saying that it has to be: package com.coreBeans; and %TOMCAT_HOME%/webapps/core/WEB-INF/classes/com/coreBeans/FormBean.class instead. Also, note bean works if the application components are moved to appropriate directories under the 'examples' folder. I'm pretty sure the bean is not the problem. It seems to me Tomcat cannot 'see' the class even though it is in the right place (I think).
